The clinical practice in Pediatrics of Chinese medicine is the first step of the students to combine the theory with the clinical practice. The optimization teaching methods for clinical practice in Pediatrics of Chinese medicine was formed by using Delphi method of the extensive consultation from experts in colleges and universities of Pediatrics of Chinese medicine. We used this teaching method in students of Beijing University of Chinese medicine in 2011. Comprehensive evaluation to the implementation of effect was from assessment from students and analysis of exam results. The results showed that based on the survey of the students in the practice, the students in the experimental group give more positive evaluation than the control group on the necessity, satisfaction and harvest in the clinical practice in pediatrics of Chinese medicine.

The microbial transformation of buflomedil by Cunninghamella blakesleana AS 3.153 was studied, as well as a microbial model which can be used to mimic metabolism of buflomedil in mammal was established. Experiments were conducted to screen the capabilities of four strains of Cunninghamella species to transform buflomedil, in which C. blakesleana AS 3.153 was selected for a preparative biotransformation. Furthermore, the microbial model was established based on the transformation condition optimization. The parent drug and its metabolites produced by C. blakesleana AS 3.153 were detected by liquid chromatography-mass spectrometry method and three metabolites were identified while two of them were new found metabolites. Two major metabolites, para-O-desmethyl buflomedil and 12-C-oxidated buflomedil, were isolated by semi-preparative HPLC. Based on the comparison between different species, the microbial transformation of buflomedil by C. blakesleana AS 3.153 is more similar to the metabolism of buflomedil in human and Beagle dog than that in rat.

Objective To investigate the application effect of nasal gastrointestinal double lumen catheter tube placement with air insufflation in mechanically ventilated patients with intra-abdominal hypertension.Methods A total of 20 patients with intra-abdominal hypertension were randomly divided into control group and observation group (n=10 in each group).Patients in control group received indwelling nasogastric tube for decompression and indwelling nasal intestine tube by air insufflation for enteral nutrition support .Patients in observation group received the dual lumen gastrointestinal tube for decompression and enteral nutrition support.The time required for catheterization,changes in intra-abdominal pressure before and after air insufflation,catheter success rate at one attempt,pain scores of patients to catheter operation, duration of decompression,enteral nutrition start time and the duration of mechanical ventilation were compared between two groups.Results The time required for catheterization,catheter air insufflation volume in observation group were significantly lower than those in control group (P <0.01);pain scores of patients to catheter operation were significantly lower in observation group than those in control group (P <0.01);There was no significantly difference in once catheter success rate,changes in intra-abdominal pressure before and after catheterization,abdominal high pressure relief time ,enteral feeding start time, and duration of mechanical ventilation between the two groups (P >0.05 ).Conclusions The technique of air insufflation has higher success rate for Indwelling nasal intestine tube in mechanically ventilated patients with intra-abdominal hypertension,and this method is safe and reliable,dual lumen gastrointestinal tube can improve patients'comfort,shorter catheterization time and reduce catheter air insufflation volume.

Objective To detect beta-human papilloma virus (HPV) and determine its genotype in actinic keratosis (AK) lesions.Methods Tissue specimens were collected from the lesions of 39 patients with AK and normal skin of 40 healthy controls.A nested PCR was performed to detect alpha-HPV and beta-HPV DNA in these specimens.The genotype of beta-HPV was determined in beta-HPV DNA-positive specimens by a common PCR using specific primers targeting 12 HPV genotypes,including HPV 5,8,15,17,19,20,21,23,36,38,49 and 80.Results The detection rate of beta-HPV DNA was 84.6％ (30/39) in the patients with AK,and 30.0％ (12/40) in the healthy controls (x2 =6.76,P ＜ 0.05),while no significant difference was observed in the detection rate of alpha-HPV DNA between the two groups (12.8％ vs.7.5％,x2 =0.91,P ＞ 0.05).HPV 38 was the predominant genotype of beta-HPV in these patients with a detection rate of 36％ (12/33),followed by HPV36.The prevalence of all the 12 genotypes of HPV was consistently low in the healthy controls.Mixed HPV infections were observed in 10 AK lesions,but in none of the healthy controls.No statistical difference was noted in the positivity rate of beta-HPV among patients at different ages,of different genders,with different occupations or clinical courses (x2 =0.53,0.94,0.81,0.73,respectively,all P ＞ 0.05).Conclusions Compared with healthy controls,the patients with AK showed a higher beta-HPV infection rate,with HPV38 as the predominant genotype.

Objective To investigate the effect of miR-27a mimic and inhibitor on proliferation and apoptosis in melanoma cell line WM239. Methods The miR-27a mimic,inhibitor and its negative control were transfected into WM239 cells. The transfection efficiency was evaluated by fluorescence microscope. The expres-sion of miR-27a was detected by real-time fluorescent quantitative PCR. The proliferation of cells was detected by MTT. The cell apoptosis and cell cycle were analyzed by flow cytometry. Results The transfection efficiency in WM239 cells was 80% to 90%. The expression of miR-27a was markedly up-regulated in miR-27a mimic group (2-△△CT value is 26. 98 ± 0. 01),with statistically significant difference(t= -1 123. 67,P=0. 00);and the miR-27a inhibitor group showed lower expression of miR-27a(2-△△CT value is 0. 96 ± 0. 02),there was no statisti-cally significant difference compared with normal control group(t=0. 04,P=0. 06). The proliferation of cells was obviously inhibited in miR-27a mimic group,and there was statistically significant difference compared with normal control group[absorbance of 72 h(0. 45 ± 0. 02)∶(0. 72 ± 0. 01),F=129. 56,P﹤0. 05]. The percent-age of WM239 cells in G0-G1 phase was increased[(74. 83 ± 1. 46)∶(63. 73 ± 1. 25),F=30. 33,P﹤0. 05], and the percentage of WM239 cells in S phase and G2-M phase were decreased[(21. 33 ± 1. 75)∶(27. 50 ± 1. 25),F=14. 98,P﹤0. 05;(3. 90 ± 1. 31)∶(8. 80 ± 2. 10),F=3. 66,P﹤0. 05]. The apoptosis rate of cells was significantly increased in miR-27a mimic group compared with normal group[(29. 67 ± 0. 91)%∶(1. 44 ± 0. 85)%,F=530. 90,P﹤0. 01],but the inhibitor group had no obvious effect on cell cycle and cell apoptosis. Conclusion MiR-27a can suppress melanoma cell proliferation and act as a tumor suppressor gene,which is rel-evant to induce cell apoptosis and block cell cycle in G0-G1 phase.

Objective To observe the clinical effects and safety of Angongniuhuang Pill (a traditional Chinese medical preparation)adjuvant to haloperidol for the treatment of Intensive Care Unit (ICU)patients in postoperative delirium.Methods A prospective study of 243 postoperative patients with delirium adimitted in Intensive Care Unit of Xinjiang Medical University First Affiliated Hospital (January 2013-December 2014),by using confusion assessment method of Intensive Care Unit (CAMICU).All of 243 patients with delirium were randomly divided into two groups by computer randomization software (SAS 9.1):group A in which patients were treated with Angongniuhuang Pill adjuvant to haloperidol and group Fin which patiets were treated with haloperidol alone.The end of two intervention methods was determined by two consecutive CAMICU showing negative or the treatment were ended up at seven days treatment.The data of general information,and the results of treatment were recorded and analized by statistical software SPSS 19.0.The measurement data was expressed as mean ±standard deviation;the comparision between two groups was tested by t test;and repeated measurement was analised by variance.Count data was described as number and constitution ratio;and intergroup comparision was tested by Chi-square test. Results There was no significant difference in general information between two groups.The delirium duration and ICU treatment time in group A were shorter than those in group F [(3.0 ±0.9)d vs.(3.8 ±1.0) d,P =0.010; (6.2 ± 1.4) d vs.(6.7 ± 1.5) d,P = 0.008].When delirium was diagnosed (T0),all patients had EEG abnormalities.As treatment went on,EEG abnormal rate gradually declined.At day one (T1),there was no statistically significant difference in EEG findings between group A and group F (95.7% vs.97.5%,P = 0.045 ).At day two (T2 )and day three (T3 ),there was statistically significant difference in EEG findings between group A and group F (65.5% vs.77.7%,P =0.038;42.2% vs.56.2%,P = 0.032).The levels of S100βprotein,interleukin-6 (IL-6),tumor necrosis factor α(TNF-α)in two groups at T0 were all elevated without noticeable difference.These markers were all deceased at T1,T2,T3,but the speed of descend in group A was relatively faster than that in group F.The differences were statistically significant (S100β:time effect P <0.01,inter-group effectp =0.002,interaction effectp =0.686;IL-6:time effect P <0.01,inter-group effectp =0.034,interaction effectp =0.01;TNF-α:time effect P <0.01,inter-group effectp =0.003,interaction effectp =0.516). The discharge rate in group A after improvement of general condition was higher than that in group F (89.7% vs.79.3%,P =0.029).The incidence of postoperative complications and mortality 28 days after operation in group A were lower than those in group F (45.7% vs.58.7%P =0.045;12.9% vs. 24.0%,P =0.028).Conclusion During the treatment of delirium,Angongniuhuang pill adjuvant to haloperidol was a better method compared with using haloperidol alone in respect of effectiveness and safety perspectives.It may be a novel approach to the treatment for delirium by the combination of Chinese and Western medicine.

Objective To discuss the effect of DNA extraction of bloodstain on the filter paper with four methods of solid phase absorption.Methods 180 bloodstain samples on the iflter paper, each one contains 1 microlitre anticoagulation peripheral venous blood, divided into 4 groups with 45 samples, respectively. All samples were treated with four methods of solid phase absorption, i.e. DNA IQ? System, D-shield sensitive DNA Extraction Kit, High efficiency Silica Bead DNA Extraction Kit and Conventional silica bead method. The concentration of DNA and the results of STR typing of four groups were compared each other.Results The concentration of DNA was 3.764±1.790μg/mL and 3.634±1.112μg/mL by using D-shield sensitive DNA Extraction Kit and High efifciency Silica Bead DNA Extraction Kit, respectively. However, the concentration of DNA by using Conventional silica bead method group (3.350±1.250) was not signiifcantly different from each other (P<0.05), while the concentration of DNA extracted with above three methods were higher than by using DNA IQ? System (1.864±1.207)(P<0.001); Signiifcant differences of peak height existed between DNA IQ? System and other three methods (P<0.001); As the same time, the peak height of samples by using High efficiency Silica Bead DNA Extraction Kit and Conventional silica bead method were signiifcantly different from D-shield sensitive DNA Extraction Kit (P<0.01).Conclusions The DNA extracted in bloodstain on the iflter paper by using D-shield sensitive DNA Extraction Kit, High efifciency Silica Bead DNA Extraction Kit and Conventional silica bead method was more than DNA IQ? System. Meanwhile, the quality of DNA using High efifciency Silica Bead DNA Extraction Kit and Conventional silica bead method may be higher.

Objective To understand the influencing factors of the post competency of health technical personnel in township hospitals in a prov-ince,so as to provide scientific reference for improving health professionals'post competency. Methods Using stratified cluster random sam-pling,1242 health professionals from township health centers and village clinics of 14 cities were extracted and then surveyed with questionnaire. Results The average score of the respondents'post competency was 3.43,which meant they could afford most of the work. Multiple linear re-gression analysis showed that the main influencing factors of the professionals'post competency included gender,age,specialty,and training. The female,senior,nursing and health-care professionals with training exhibited a better post competency. Conclusion To realize the further develop-ment of professionals'post competency,medical students should not only be early clinical and more clinical,but also actively participate in the training and continue the education after entering the clinic. On the other hand ,the government should define the function orientation of the town-ship healthy centers and explore human resource management mode based on the post competency.
